Summoners War: Chronicles

I found a bug in the game's Storage, when I try to place items stocked without anything in the chest, the quantity counter simply does not appear, but when I place 2 individual items first, it works normally.

when there are 2 items in the left chest the counter appears.

when the left chest is empty and you try to place accumulated items such as potions, the quantity counter simply does not appear, it just selects the item.
